Problems solved by technology

However, the camera sends the complete shooting image information to the recording and broadcasting host, but the recording and broadcasting host only needs to capture a part of the image, which causes a huge waste of bandwidth in transmission resources, and is easy to encounter the bandwidth limit of the transmission line. When using 4K or 8K resolution cameras, the bandwidth of the transmission link will become a bottleneck

Abstract

The invention provides a method and system for realizing multi-scene shooting of an electronic pan / tilt. The front-end device receives editing instructions from the user's host computer, and obtains multiple specific resolutions through cutting and zooming operations in a high-resolution original video image according to the editing instructions. Scene video images of multiple specific resolutions are spliced ​​into one video image by splicing, and a non-encoded video image is sent to the user’s host through a physical transmission line, and the user’s host is separated according to the splicing position information. For multiple video images of different scenes, the user host performs image data processing on the video images of multiple different scenes and then encodes them once to generate high-quality video playback files or streaming media data. Efficient use of transmission line bandwidth, one-time encoding to generate high-quality video playback files, easy system installation and operation and maintenance, improve overall data processing and transmission efficiency, and effectively reduce the overall cost of the system.

Description

technical field [0001] The invention belongs to the technical field of video monitoring and recording and broadcasting, and in particular relates to a method and system for realizing multi-scene shooting of an electronic pan / tilt. Background technique [0002] In the current implementation plan of normalized recording and broadcasting classrooms, in order to simplify deployment, it is often necessary to use one camera to simultaneously capture at least two scenes, such as close-ups of teachers, panoramic views of teachers, close-ups of blackboard writing and other scenes. [0003] The current multi-scene shooting solution is to use the PTZ network camera to crop the captured images. After receiving the user control instructions from the recording and broadcasting host, the PTZ network camera encodes the specific shooting area and transmits it to the recording and broadcasting host through the IP network. After the recording and broadcasting host receives the encoded video fo...
